When configuring a data point you can apply a label that can provide additional information. For example, the following line chart contains data point labels that show the data point's Y-axis value, as well as a data point-level tooltip:
A line chart with data point labels and a tooltip.
A label applied to a data point will supersede the label applied to the associated series.
To add and customise labels, open the Data Point Label panel in the Series Data Point interface:
Configuring a data point label.
This panel is split into two tabs, the first of which is General where you will find the following options:
- Label Text - The text to use as the label. This can also include dynamic keywords values.
- Show the Data Point Value as Label - Tick this to use the value of the data point as the label.
- Data Point Value Format - If using the data point value for the label, this field enables you to provide a standard format string. A complete list of standard numeric formatting options can be found in this MSDN article.
The second tab is Interactivity, which contains the following options:
- Label ToolTip - Enter the text to use as a tooltip. This can also include dynamic keywords values.
- Data Point URL - Enter the URL to use as the hyperlink. If the link should open in another browser window, tick the Open URL in New Window check box.
